"It went perfectly. We reached out via Angie’s list message and had a reply within minutes. Service was scheduled for the next day. Troubleshooting quickly identified a failed power inverter board, but also determined that the compressor itself was not damaged and did not need repair (honesty!). He had the part on the truck and it was replaced quickly. In addition, he found a VERY small leak from the water tubing that was only present when dispensing water. This was likely the root cause of the board failure. Awesome work! He also cleaned the coil with an air duster while he was back there. He went out of his way to make sure the fridge was good to go. Highly recommended!!!!"

"I had an excellent experience with this HVAC company! They installed 3 central A/C units in my building, and everything was done professionally and efficiently. Special thanks to Angel and Martin for their great work, professionalism, and attention to detail. Highly recommend!"
Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
